/* ==========================================================================
   Styles for the SEO case pages (/vpn/<slug>/).

   Kept apart from style.css on purpose: the landing page has its own long
   stylesheet, and these pages load a lighter, article-shaped layout. Design
   tokens are shared, so the two look like one site.
